Using jQuery to replace form inputs with their value

Question

Can jQuery be used in order to tranform this code:

<table>
    <tr>
        <td><input type="text" name="a1" value="Input value 1" /></td>
        <td><input type="text" name="a2" value="Input value 2" /></td>
        ...
        <td><input type="text" name="a10" value="Input value 10" /></td>
    </tr>
</table>

into this code:

<table>
    <tr>
        <td>Input value 1</td>
        <td>Input value 2</td>
        ...
        <td>Input value 10</td>
    </tr>
</table>

Thanks.

Yes it can. What errors are you getting with the code you have written? — Rory McCrossan

Try to narrow down your question. Are you screen scraping another website, are you trying to change your own? What attempts have you made? — Raul Marengo

The answer you've accepted (boobiq's) has a pretty big issue, see scessor's answer for a (much) better solution. See my comment on that answer for details. — T.J. Crowder

$('td').each(function() {
    $(this).text($(this).find('input').val());
});

Also see this example.

@T.J.Crowder - I suppose it's not possible that interpreting the HTML instead of encoding it as text may be desirable? I can see the logic of $.text(), but I don't think $.html() is inherently wrong.

$('td').each(function(){
  var elem = $(this);
  elem.text(elem.find('input[type="text"]').val());
});

in this case, you can use for example:

$('input[type="text"]').each(function()
{
    $(this).parent('td').html($(this).val());
});

untested, but that should be enough

...and if the value contains HTML special characters?

Rory McCrossan Over a year ago

While this works, scessor's answer has much better performance, and does not have the problem of having to encode HTML characters.

Jared Farrish Over a year ago

@RoryMcCrossan - The issue that matters is performance; the special characters IMO is somewhat of a red-herring. $.text() I assume would have better performance for larger tables. The best answer would specify that $.html() should be used if markup should be interpreted, otherwise use $.text().

T.J. Crowder Over a year ago

@JaredFarrish: Completely disagree that the special characters are a red herring. That's how we get exploits and security holes. What if I put <script src="destroy.js"></script> in a text field and this code is run? What then? We have the tools to prevent that attack vector, why in heaven's name would we not use them?

@JaredFarrish: LOL!! ;-) I can't even deny it. Blast.
